You can use scrapbook paper, Christmas paper, left over Christmas Cards.. whatever you have.
Cut the 2 x 4's to about 6 inches tall and sand them down really well. Don't want any splinters! Paint them up with your colour choice, modge podge some paper on the side and add letters.

I got these little wooden letters from Michael's Craft Store. The were hot glued to the dried modge podge.

I love them! I love that you used wood letters as I've seen these done with vinyl lettering but I don't have one of those machines. I actually like the depth the wood letters give these! Great for a quick and simple project, too. Love the papers you used. You've reminded me that I have a kit something like this that I need to pull out and do {before it's too late!}.

Hi Lisa! This is too funny. Just last night I was going thru a bunch of old stuff to see what I could use in my booth and for an upcoming show. I came across a bag from Michael's. In it were four wooden letter exactly like those (but spelled my oldest daughter's name M-A-C-Y). I was trying to think of something unique to do with them and you've just sparked an idea I can do in their "Paris Apt" style room! I've had another daughter who just turned 6 so I guess I need to return and get G-R-A-C-E!)Thanks for the inspiration!Blessings to You,Missy
